A method includes acquiring timing analysis data associated with a cell and activity data of one or more inputs of the cell, determining a glitch toggle rate for an output of the cell based on the activity data of the one or more inputs of the cell and the timing analysis data, and estimating a glitch power based on at least the glitch toggle rate.
Legal claims defining the scope of protection, as filed with the USPTO.
3. The method of claim 1, wherein the activity data includes a static probability and a toggle rate of the one or more inputs of the cell.
4. The method of claim 1, wherein the glitch toggle rate is determined based on a binary decision diagram (BDD), the BDD representing a function of the cell.
8. The method of claim 7, wherein a width of the adjusted timing window is a function of a cell delay, a clock period, or a threshold value.
10. The method of claim 7, wherein the adjusted timing window includes an area of the timing window having a high probability density for the arrival times of the input signals associated with the one or more inputs of the cell.
12. The method of claim 1, wherein the glitch toggle rate includes functional toggles and glitch toggles propagated for two or less levels.
15. The system of claim 13, wherein the activity data includes a static probability and a toggle rate of the one or more inputs of the cell.
16. The system of claim 13, wherein the glitch toggle rate is determined based on a binary decision diagram (BDD), the BDD representing a function of the cell.
